Evaluation of Reaction Times to Sound Stimuli on Mobile Devices

Authors: György Wersényi, Hunor Nagy and Ádám Csapó Abstract: When developing new devices for assistive technology, it is important to consider auditory response times to different kinds of warning and navigational sounds. Perception, processing and action following the presentation of auditory stimuli depends on several parameters, the most important being the stimuli themselves and the method used… Continue Reading Evaluation of Reaction Times to Sound Stimuli on Mobile Devices

Haptic-Auditory Perceptual Feedback Based Training for Improving the Spatial Acoustic Resolution of the Visually Impaired People

Authors: Oana Bălan, Alin Moldoveanu Hunor Nagy, György Wersényi Nicolae Botezatu, Andrei Stan and Robert-Gabriel Lupu Abstract: 3D binaural sounds play an important role in the development of navigational systems for the blind people. The use of generic HRTFs in virtual auditory displays significantly affects the acoustic spatial resolution and the listener’s ability to make localization judgments… Continue Reading Haptic-Auditory Perceptual Feedback Based Training for Improving the Spatial Acoustic Resolution of the Visually Impaired People

Evaluation of the Range of Head Movements in Measurements and Recordings with Human Subjects using Head-Tracking Sensors

Authors: G. Wersényi and J. Wilson Abstract: Measurements for spatial hearing research, binaural recordings, virtual reality techniques etc. often rely on Head-Related Transfer Functions of human subjects, head-tracking techniques etc. Individually measured HRTFs and recordings on human heads may result in more accurate localization and sound field rendering. On the other hand, the measurement and recording procedure… Continue Reading Evaluation of the Range of Head Movements in Measurements and Recordings with Human Subjects using Head-Tracking Sensors
